            Bug ID: 40653
           Summary: Inline _byteswap_* functions for optimized build
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org
          Reporter: Tom.Tan at microsoft.com
                CC: llvm-bugs at lists.llvm.org, neeilans at live.com,

_byteswap_* series functions (_byteswap_uint64, _byteswap_ulong,
_byteswap_ushort) are provided as library functions in libucrt.lib, but MSVC
doesn't inline them for optimized build. It will be great to inline them in
clang-cl.exe for optimized build.
